While fountain pens are highly regarded because-of their convenience andportability, they are all subject to several objections,

one of which is the small quantity of ink which can be carried'by them,requiring frequent illing and very often at inopportuna times; moreoverthe act of lling is commonly accompanied by loss of ink and soiling ofthe lingers. A)

It also occurs, at times, that the use of another color of ink isdesirable than that ordinarily supplied, or that a' liner or coarser penpoint be preferred, which is' net possible with ordinary commercialfountain ens.

p It is therefore an object of the present invention to provide a pencapable of containing a lar er volume of Writing ink than 1s usual anwhich is so arranged as to entirely dispense with the ordinary 'fillingmeans, the ink being held in a removable receptacle for which othersofthe same klnd ma be readily lea age of the ink.

A further feature is in the provision of means whereby a single writingimplement maybe used with differently colored inks, or that the same inkmay be supplied by pen points of different degrees of pliability andwidth of line produced.

Another purpose is to produce a fountain pen in which the body and capare alike in diameter, thus avoiding the bulky appearance of theordinary pens.

Another purpose is `the provision of a connecting sleeve or adaptorwhich may be attachedto any fountain pen for the purpose of producing-aduplex writing implement. I f

These severall important objects are .attained by the novel constructionand combination of parts as hereinafter described and shown in theannexed drawings, formsubstituted without loss or- 19:9. serial No.311,938.

ing a material part of this disclosure, and in which:

Fig. 1 is a longitudinal sectional view of a pen made in conformityvwith'the invention.. v

Fig. 2 is a similar view showin a modilied construction wherein two inependent pens are combined.

Fig. 3 is a side elevational view of the removable ink reservoir as usedtherein.

Fig. 4 is a fragmentary view of a modiied construction wherein thecapsule is entirely encased within the barrel.

The pen body consists of a tubular barrel 10 having a rounded frontportion 11 blending into a screw threaded element 12 from which extendsa reduced collar 13 and reaching outward therebeyond a common pen pointor nib 14. i

The opposite end of the barrel 10 is square across and contains a shortinternal screw thread 15.

Neatly `fitting the bore of the barrel 10 isla rigid tube 16 provided.at one end with a thread 17 engaged by a cap 18 which when the tube orcapsule is to be entered in the barrel, is removed.

At the opposite end of the tube is another thread 19 ending at theshoulder of the knurled head 20. The thread 19 engages in the internalthread 15 of the barrel and forms a leak tight joint.

A cap 31 is bored to receive the pen point and adjacent elements, thecap being provided with internal screw threads to engage the barrelthreads 12 or the reservoir threads 21 in accordance with the end of theimplement to which it may be applied, the cap being furnished with narytype.

In the modified form shown in' Fig. 2, the outer threaded element 21 isbored to provide a recess 23 to receive -the nib of the pen 14 carriedin a structure the exact counterpart of that previously described and.to which have been appended prime numbers for the purpose oillustration, the difference being that the barrels 10-10 and 16-16 areshorter in'length.

A connecting sleeve 24 tubular to receive a clip 22 of ordithe pen pointand adjacent elements is rovided wlth internal screw threads on othends; one end adapted to engage the barre-l 12T and the other end toengage the barrel thread 21.

This arrangement permits of the use of two diierently colored inks or oftwo pens unlike in their degree of ineness, andproduces a duplex writingimplement. This connecting sleeve might also be connected to threads onthe back of any standard fountain pens for the purpcseof producing aduplex, and is in nowise restricted to be used in connection wvith thecapsule 16. This connecting sleeve when so used cooperates with the endof one pen to ferm a cap fora second pen.

In the modified form shownv in Fig. 4, the rear end of the barrel10contains a short external screw thread 26 to receive the threads of acap or closure 25, this cap also being provided with similar externalscrew threads 2101 to be engaged by the cap 31 or the connector sleeve24, as desired.

In this modification, the capsule or car-` tridge 16a'is entirely smoothand closed at one end to fit within the barrel 10 of the pen, theopposite end being provided with screw threads 17 to receive the cap18,'as previously described.

In operation, when the ink needs renewing, the empty receptacle iswithdrawn by unscrewing it from the barrel, or in the case wherereceptacle 16a: is used, the cap 25 is unscrewed, the cap 18 removed'from a receptacle to be substituted and then inserted )in the barrel,at that time in anV inverted position with the pen in a substantiallyupright position. e Due tothe fact that the cap 31 is equivalent in sizewith thevpen barrel, less space is occupied anda neater appearanceobtained.

While certain preferred embodiments of this device have been shown anddescribed, it will be understood that changes in the form, arrangements,proportions, sizes and detailsthereof may be made without departing fromthe scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is: Y i

1. The combination with two independent fountainpens provided with screwthreads movabl engaged with the front or rear vends o either fountainpen whereby both pens may be rigidly joined together with pens opposedto produce a dup ex writing lmplement, said sleeve adapted at -othertimes to act -as a cap for one of the ens.

3. As Van article of `manufacture or use with two independent fountainpens which are to be joined and used as a duplex writing implement, aconnecting sleeve adapted to be selectively removably engaged with therear ends of both fountain pens, or with front end of one and the rearend of the other, whereby in the iirst instance both pens are presentedfor use and in the second instance the said sleeve acts as a cap for oneof the pens.
